[FFmpeg-devel] [PATCH 3/3] avformat/utils: Set stream side-data size even without side-data

Was the earlier behaviour actually a bug (I think so) or is this new
behaviour something that should be explicitly documented?

Btw, the stream and packet side-data APIs differ in two more ways:
av_packet_new_side_data() adds padding to the buffer and zeroes it
whereas av_stream_new_side_data() does not. Should this be unified?
